Description
Visocolor™ alpha is the most simple titrimetric test kit, which is suitable for visual evaluation only. With multicomponent reagents, the test kits are limited in precision and accuracy but represent an inexpensive method for screening tests of non-turbid and uncolored water samples. The reagent bottles are packed in practical blister packs with the test instructions on the back.
- Carbonate hardness is calcium and magnesium ions that present as carbonate or hydrogen carbonate
- Reaction principle analogous to APHA 2320, DIN EN ISO 9963-1 C23 and -2 C24
- Used specimens can be flushed down the drain with tap water
